First, My rig weights about 3.25 lb but I am going to say 3 lb for a slightly negatively buoyant rig. I plan on either using PVC pipe, DivinyCell, or that Stix brand stuff to add buoyancy. I'm interested to hear your opinions of all of these as well.
3lb = 1.36 kg
Neutral buoyancy is when Normal force (Mass x Gravity) = Buoyancy force (Gravity x Density of fluid x Volume displaced)
1.36 kg x 9.8 m/s^2 = 13.36 N
So, I need to create about 13.36 N of lift to get this rig neutrally buoyant.
13.36 N = 9.8 m/s^2 x 1029 kg/m^3 (density of saltwater) x V
If this is correct, I should need a volume of 0.00132 M^3 which I don't believe is right..
I'm a biologist so not much physics experience. Hopefully, there is an engineer or someone around to kick my ass with these calculations lol.
Thanks for the help and happy diving everyone.
